    "Hello, #{name}!"
module.exports = HelloWorld

Get mentored the CoffeeScript way

Every language has its own way of doing things. CoffeeScript is no different. Our mentors will help you learn to think like a CoffeeScript developer and how to write idiomatic code in CoffeeScript. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in CoffeeScript - they'll help you discover the things you don't know that you don't know.
